Have UTI. Messed up taking the pills

After a week of being in constant pain, I went to see my doctor and got antibiotics for my UTI. I have them frequently, especially after sex. My doctor prescribed me Sulfamethoxazole Trimethoprim with 1 pill twice a day for three days.

I accidentally read the directions wrong and ended up taking 2 pills at once, and just before I took one. So I've taken 3 pills in one day instead of two. The disadvantage to this now, is that I only have pills for one more day, instead of two.

Does this mean I won't get treated if I'm not taking it the third day?
